STAGES CYCLING Power Meter R Shimano Ultegra R8100
The Stages Power Meter R for the Shimano Ultegra R8100 crank. The power meter is pre-assembled on a right Shimano Ultegra R8100 crank arm with crankshaft and can be exchanged extremely quickly and easily for the right crank arm of the existing crankset. If you already have a power meter L for the R8100 crank, you can upgrade your power meter to a system with double-sided measurement with the Stages Powermeter R.
All features from the current LR (Left-Right) power meter with power measurement on both sides have been integrated into the R (Right) power meter. Not only the software, but also the hardware has been revised. In this way, the measurement accuracy could be increased to +-1.5%. The antenna has also become stronger and sends the data with 6 times higher intensity, which reduces the risk of dropouts. The R power meter is also compatible with even more bike computers. The integrated cadence sensor has also been upgraded to measure values even more precisely. Optionally, the cadence can now also be measured using a magnet. As a positive side effect, the new hardware ensures a weight reduction of 5 grams compared to the previous version.
Active temperature compensation ensures that the Stages power meter measures the power precisely, even with large temperature fluctuations. The Stages power meter is compatible with all ANT+-capable bike computers and the latest smartphone models via the ANT+ and Bluetooth Smart transmission standards. Firmware upgrades can be carried out quickly and easily thanks to wireless transmission to the power meter.
An integrated LED display visualizes the battery status and the calibration result even without a connection to an app or the bike computer. In order to be prepared for bad weather, the Stages LR power meter is waterproof according to the IPX7 standard (temporary submersion).
NOTE: The left crank arm is not included.
